The NB-N102 low residue nebulizer cup is designed as a replacement or configuration accessory for nebulizer systems. It supports high performance aerosol delivery with liquid residue below 0.5 ml, helping distributors build flexible respiratory care kits for different treatment preferences, patient groups, and after-sales replacement needs. As an accessory item for compressor or oxygen-related nebulizer applications, it is suitable for catalog expansion, spare-parts pages, and bundled product offerings where clear compatibility, material quality, and stable supply are important purchase factors.
